There's not much to the article, but I enjoyed the sentiment expressed. I started playing golf when I was probably nine years old, and didn't play a regulation course or hit a wood until I was 13-14 years old. Once or twice a month, my dad would take my brother and me to the Arcadia (CA) three-par. We would load our clubs (maybe four irons per, plus putters) into a bag and drag a pull-cart for 18 holes. When I was in about sixth grade, some friends and I would get one of our moms to drop us off at the course during the summer about once a week. It wasn't until I was almost a freshman in high school that I started playing "big" courses. A few years ago I went back and played again with my dad, one of the last rounds we'll ever play together, and had a great time.
Par threes are a great place to teach kids the game, to learn the swing, and more importantly to learn course etiquette in a fairly low pressure environment.
